		/**
		 * DataTables API class - used to control and interface with  one or more
		 * DataTables enhanced tables.
		 *
		 * The API class is heavily based on jQuery, presenting a chainable interface
		 * that you can use to interact with tables. Each instance of the API class has
		 * a "context" - i.e. the tables that it will operate on. This could be a single
		 * table, all tables on a page or a sub-set thereof.
		 *
		 * Additionally the API is designed to allow you to easily work with the data in
		 * the tables, retrieving and manipulating it as required. This is done by
		 * presenting the API class as an array like interface. The contents of the
		 * array depend upon the actions requested by each method (for example
		 * `rows().nodes()` will return an array of nodes, while `rows().data()` will
		 * return an array of objects or arrays depending upon your table's
		 * configuration). The API object has a number of array like methods (`push`,
		 * `pop`, `reverse` etc) as well as additional helper methods (`each`, `pluck`,
		 * `unique` etc) to assist your working with the data held in a table.
		 *
		 * Most methods (those which return an Api instance) are chainable, which means
		 * the return from a method call also has all of the methods available that the
		 * top level object had. For example, these two calls are equivalent:
		 *
		 *     // Not chained
		 *     api.row.add( {...} );
		 *     api.draw();
		 *
		 *     // Chained
		 *     api.row.add( {...} ).draw();
		 *
		 * @class DataTable.Api
		 * @param {array|object|string|jQuery} context DataTable identifier. This is
		 *   used to define which DataTables enhanced tables this API will operate on.
		 *   Can be one of:
		 *
		 *   * `string` - jQuery selector. Any DataTables' matching the given selector
		 *     with be found and used.
		 *   * `node` - `TABLE` node which has already been formed into a DataTable.
		 *   * `jQuery` - A jQuery object of `TABLE` nodes.
		 *   * `object` - DataTables settings object
		 * @param {array} [data] Data to initialise the Api instance with.
		 *
		 * @example
		 *   // Direct initialisation during DataTables construction
		 *   var api = $('#example').DataTable();
		 *
		 * @example
		 *   // Initialisation using a DataTables jQuery object
		 *   var api = $('#example').dataTable().api();
		 *
		 * @example
		 *   // Initialisation as a constructor
		 *   var api = new $.fn.DataTable.Api( 'table.dataTable' );

			/**
			 * DataTables can be instructed to load data to display in the table from a

			 * * `string` - Set the URL from where the data should be loaded from.
			 * * `object` - Define properties for `jQuery.ajax`.
			 * * `function` - Custom data get function
			 *
			 * `string`
			 * --------
			 *
			 * As a string, the `ajax` property simply defines the URL from which
			 * DataTables will load data.
			 *
			 * `object`
			 * --------
			 *
			 * As an object, the parameters in the object are passed to
			 * [jQuery.ajax](http://api.jquery.com/jQuery.ajax/) allowing fine control
			 * of the Ajax request. DataTables has a number of default parameters which
			 * you can override using this option. Please refer to the jQuery
			 * documentation for a full description of the options available, although
			 * the following parameters provide additional options in DataTables or
			 * require special consideration:
			 *
			 * * `data` - As with jQuery, `data` can be provided as an object, but it
			 *   can also be used as a function to manipulate the data DataTables sends
			 *   to the server. The function takes a single parameter, an object of
			 *   parameters with the values that DataTables has readied for sending. An
			 *   object may be returned which will be merged into the DataTables
			 *   defaults, or you can add the items to the object that was passed in and
			 *   not return anything from the function. This supersedes `fnServerParams`
			 *   from DataTables 1.9-.
			 *
			 * * `dataSrc` - By default DataTables will look for the property `data` (or
			 *   `aaData` for compatibility with DataTables 1.9-) when obtaining data
			 *   from an Ajax source or for server-side processing - this parameter
			 *   allows that property to be changed. You can use Javascript dotted
			 *   object notation to get a data source for multiple levels of nesting, or
			 *   it my be used as a function. As a function it takes a single parameter,
			 *   the JSON returned from the server, which can be manipulated as
			 *   required, with the returned value being that used by DataTables as the
			 *   data source for the table. This supersedes `sAjaxDataProp` from

			 * ----------

			 * As a function, making the Ajax call is left up to yourself allowing

			 *
			 * The function is given four parameters and no return is required. The
			 * parameters are:
			 *
			 * 1. _object_ - Data to send to the server
			 * 2. _function_ - Callback function that must be executed when the required
			 *    data has been obtained. That data should be passed into the callback
			 *    as the only parameter
			 * 3. _object_ - DataTables settings object for the table
			 *
			 * Note that this supersedes `fnServerData` from DataTables 1.9-.

			 */


			/**
			 * This property can be used to read data from any data source property,
			 * including deeply nested objects / properties. `data` can be given in a
			 * number of different ways which effect its behaviour:
			 *
			 * * `integer` - treated as an array index for the data source. This is the
			 *   default that DataTables uses (incrementally increased for each column).
			 * * `string` - read an object property from the data source. There are
			 *   three 'special' options that can be used in the string to alter how
			 *   DataTables reads the data from the source object:
			 *    * `.` - Dotted Javascript notation. Just as you use a `.` in
			 *      Javascript to read from nested objects, so to can the options
			 *      specified in `data`. For example: `browser.version` or
			 *      `browser.name`. If your object parameter name contains a period, use
			 *      `\\` to escape it - i.e. `first\\.name`.
			 *    * `[]` - Array notation. DataTables can automatically combine data
			 *      from and array source, joining the data with the characters provided
			 *      between the two brackets. For example: `name[, ]` would provide a
			 *      comma-space separated list from the source array. If no characters
			 *      are provided between the brackets, the original array source is
			 *      returned.
			 *    * `()` - Function notation. Adding `()` to the end of a parameter will
			 *      execute a function of the name given. For example: `browser()` for a
			 *      simple function on the data source, `browser.version()` for a
			 *      function in a nested property or even `browser().version` to get an
			 *      object property if the function called returns an object. Note that
			 *      function notation is recommended for use in `render` rather than
			 *      `data` as it is much simpler to use as a renderer.
			 * * `null` - use the original data source for the row rather than plucking
			 *   data directly from it. This action has effects on two other
			 *   initialisation options:
			 *    * `defaultContent` - When null is given as the `data` option and
			 *      `defaultContent` is specified for the column, the value defined by
			 *      `defaultContent` will be used for the cell.
			 *    * `render` - When null is used for the `data` option and the `render`
			 *      option is specified for the column, the whole data source for the
			 *      row is used for the renderer.
			 * * `function` - the function given will be executed whenever DataTables
			 *   needs to set or get the data for a cell in the column. The function
			 *   takes three parameters:
			 *    * Parameters:
			 *      * `{array|object}` The data source for the row
			 *      * `{string}` The type call data requested - this will be 'set' when
			 *        setting data or 'filter', 'display', 'type', 'sort' or undefined
			 *        when gathering data. Note that when `undefined` is given for the
			 *        type DataTables expects to get the raw data for the object back<
			 *      * `{*}` Data to set when the second parameter is 'set'.
			 *    * Return:
			 *      * The return value from the function is not required when 'set' is
			 *        the type of call, but otherwise the return is what will be used
			 *        for the data requested.
			 *
			 * Note that `data` is a getter and setter option. If you just require
			 * formatting of data for output, you will likely want to use `render` which
			 * is simply a getter and thus simpler to use.
			 *
			 * Note that prior to DataTables 1.9.2 `data` was called `mDataProp`. The
			 * name change reflects the flexibility of this property and is consistent
			 * with the naming of mRender. If 'mDataProp' is given, then it will still
			 * be used by DataTables, as it automatically maps the old name to the new
			 * if required.

	/**
	 * Scroller is a virtual rendering plug-in for DataTables which allows large
	 * datasets to be drawn on screen every quickly. What the virtual rendering means
	 * is that only the visible portion of the table (and a bit to either side to make
	 * the scrolling smooth) is drawn, while the scrolling container gives the
	 * visual impression that the whole table is visible. This is done by making use
	 * of the pagination abilities of DataTables and moving the table around in the
	 * scrolling container DataTables adds to the page. The scrolling container is
	 * forced to the height it would be for the full table display using an extra
	 * element.
	 *
	 * Note that rows in the table MUST all be the same height. Information in a cell
	 * which expands on to multiple lines will cause some odd behaviour in the scrolling.
	 *
	 * Scroller is initialised by simply including the letter 'S' in the sDom for the
	 * table you want to have this feature enabled on. Note that the 'S' must come
	 * AFTER the 't' parameter in `dom`.
	 *
	 * Key features include:
	 *   <ul class="limit_length">
	 *     <li>Speed! The aim of Scroller for DataTables is to make rendering large data sets fast</li>
	 *     <li>Full compatibility with deferred rendering in DataTables for maximum speed</li>
	 *     <li>Display millions of rows</li>
	 *     <li>Integration with state saving in DataTables (scrolling position is saved)</li>

	/*
	
	Select is a collection of API methods, event handlers, event emitters and
	buttons (for the `Buttons` extension) for DataTables. It provides the following
	features, with an overview of how they are implemented:
	
	## Selection of rows, columns and cells. Whether an item is selected or not is
	   stored in:
	
	* rows: a `_select_selected` property which contains a boolean value of the
	  DataTables' `aoData` object for each row
	* columns: a `_select_selected` property which contains a boolean value of the
	  DataTables' `aoColumns` object for each column
	* cells: a `_selected_cells` property which contains an array of boolean values
	  of the `aoData` object for each row. The array is the same length as the
	  columns array, with each element of it representing a cell.
	
	This method of using boolean flags allows Select to operate when nodes have not
	been created for rows / cells (DataTables' defer rendering feature).
	
	## API methods
	
	A range of API methods are available for triggering selection and de-selection
	of rows. Methods are also available to configure the selection events that can
	be triggered by an end user (such as which items are to be selected). To a large
	extent, these of API methods *is* Select. It is basically a collection of helper
	functions that can be used to select items in a DataTable.
	
	Configuration of select is held in the object `_select` which is attached to the
	DataTables settings object on initialisation. Select being available on a table
	is not optional when Select is loaded, but its default is for selection only to
	be available via the API - so the end user wouldn't be able to select rows
	without additional configuration.
	
	The `_select` object contains the following properties:
	
	```
	{
		items:string     - Can be `rows`, `columns` or `cells`. Defines what item 
						   will be selected if the user is allowed to activate row
						   selection using the mouse.
		style:string     - Can be `none`, `single`, `multi` or `os`. Defines the
						   interaction style when selecting items
		blurable:boolean - If row selection can be cleared by clicking outside of
						   the table
		info:boolean     - If the selection summary should be shown in the table
						   information elements
	}
	```
	
	In addition to the API methods, Select also extends the DataTables selector
	options for rows, columns and cells adding a `selected` option to the selector
	options object, allowing the developer to select only selected items or
	unselected items.
	
	## Mouse selection of items
	
	Clicking on items can be used to select items. This is done by a simple event
	handler that will select the items using the API methods.
